Abstract

The demand for a rear reflective material is continuing according to the expansion of the bifacial soar module and the effect on the re-reflection of the ground using a back sheet that is not used due to the increase in the supply of the bifacial solar module was confirmed. For analysis, a bifacial solar module with an output of 445W was connected to a single inverter of 49.84kW, and analysis of each two inverters was carried out. In the analysis of the results, it was confirmed that the generation amount increased by 5.25% compared to the case where the back sheet reflective film was not installed and it was confirmed that the increase in the generation amount was the noon time when strong solar radiation was irradiated, not the time of sunrise and sunset.
